Trail and error only way to learn.
And double checking everything. Do not rush. I did once and broke the plastic piece that covers the sector gear behind the trigger.
As for the spring length, the spring is probably not wound as tight than the stock one and/or made of a thinner, less resistant metal. This is how it can be longer but produces less force.
